Can Anyone Suggest a Good Switch?

wgadmin asks: "I am a sysadmin for a 500-node Linux cluster. We are doubling the size of our compute nodes, so, as a consequence, we need a new switch. We currently have a Foundry FastIron 1500 -- however, a) it doesn't have enough ports (only 208) and b) it is extremely unreliable. We want something that's solid as a rock. We process mostly serial jobs. And we will probably require ~320 ports. What's everyone using for their HPC clusters? There's so many high performance switches on the market, we hardly know where to start."

Yes, these guys are awesome. We just got one of their switches for our cluster. All ports are line speed, no over subscription. They are also soon to announce some higher density line cards for their existing chassis in the upcoming months. Definitely give them a look.
